Automatic clutch control method and device

摘要

The present invention relates to a method to automatically control a power transmission of a vehicle, in particular of a saddle-riding type vehicle, performing on and off operation of a friction clutch provided between a driving side power transmission mechanism and a driven side power transmission mechanism, and shifting of gears of a transmission, wherein a clutch connecting speed is controlled on the basis of a reduction rate of a difference in rotational numbers of the driving side power transmission mechanism and the driven side power transmission mechanism during half-clutch control
